how to calculate using financial calculator?

You are evaluating two different silicon wafer milling machines. The Techron I costs $234,000, has a three-year life, and has pretax operating costs of $61,000 per year. The Techron Il costs $410,000, has a five-year life, and has pretax operating costs of $34,000 per year. For both milling machines, use straight-line depreciation to zero over the project's life and assume a salvage value of $38,000. If your tax rate is 35 percent and your discount rate is 10 percent, compute the EAC for both machines. (Your answers should be a negative value and indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) EAC $ Techron I Techron II $ Which machine should you choose? Techron 1 O Techron
